Boosting seawater alkalinity could help communities tackle local carbon emissions, researchers argue‎

When scientists discovered that increasing the ocean's natural alkalinity could enhance seawater's capacity to absorb and store carbon dioxide (CO₂), the idea quickly gained attention as a potential geoengineering solution to climate change. Early visions suggested it could remove gigatonnes of CO₂ from the atmosphere each year. But the reality is far more complex.
